An articulated mechanism system includes a plurality of fingers (articulated mechanisms) arranged in parallel, each of which has a mounting member, a first digital part rotatably connected to the mounting member by a first connecting part, a second digital part rotatably connected to the first digital part by a second connecting part, and a first driving part rotatably connected to the second digital part by a fourth connecting part and connected to a third connecting part. By extruding the third connecting part toward the fourth connecting part, the first digital part and the second digital part are integrally rotated about the first connecting part, or the second digital part is rotated about the second connecting part when the rotation of the first digital part is blocked. The third connecting parts are driven by a single driving mechanism for the same distance and in the same direction at a time.
